Gaps in the existing public health informatics training programs: a challenge to the development of a skilled global workforce.

The objective of this study was to explore public health informatics (PHI) training programs that currently exist to meet the growing demand for a trained global workforce. We used several search engines, scientific databases, and the websites of informatics organizations; sources included PubMed, Google, the American Medical Informatics Organization, and the International Medical Informatics Organization. The search was conducted from May to July 2011 and from January to February 2012 using key words such as informatics, public health informatics, or biomedical informatics along with academic programs, training, certificate, graduate programs, or postgraduate programs. Course titles and catalog descriptions were gathered from the program or institution websites. Variables included PHI program categories, location and mode of delivery, program credits, and costs. Each course was then categorized based on its title and description as available on the Internet. Finally, we matched course titles and descriptions with the competencies for PHIs determined by Centers for Disease Control and Prevention (CDC). Descriptive analysis was performed to report means and frequency distributions for continuous and categorical variables. Stratified analysis was performed to explore average credits and cost per credit among both the public and private institutions. Fifteen PHI programs were identified across 13 different institutions, the majority of which were US-based. The average number of credits and the associated costs required to obtain PHI training were much higher in private as compared to public institutions. The study results suggest that a need for online contextual and cost-effective PHI training programs exists to address the growing needs of professionals worldwide who are using technology to improve public health in their respective countries.
